Sinclair Pro Series Hydroleca LECA Pebbles 8-12mm 50L are premium lightweight expanded clay aggregate (LECA) pebbles designed to improve drainage, aeration and root health across a wide range of growing applications. Ideal for hydroponic systems, houseplants, container gardening and decorative displays, these versatile clay pebbles provide a clean, stable and reusable growing medium for healthier plants.

The porous structure of Hydroleca absorbs and stores moisture while maintaining excellent airflow around the root zone, helping to reduce the risk of waterlogging and root rot. Suitable for use as a standalone hydroponic growing medium, a drainage layer in pots, or as a decorative top dressing, these expanded clay pebbles offer exceptional versatility for professional growers and home gardeners alike.

Their lightweight nature makes handling easy, while their durability ensures long-lasting performance across multiple growing cycles.
